Re: Oi Microsoft
That's not how to do it. Each time Microsoft updates/re-releases that update, it will appear again to be installed, even after you hid it. Furthermore, who knows what other sneaky updates Microsoft will release in the near future to load Windows 10 on people's computers.
Instead of uninstalling/hiding certain updates, it is much more effective to leave them installed and simply opt your computer out of the upgrade: http://win10epicfail.proboards.com/thread/46/completely-disable-icon-automatic-upgrade
